Which country is Loopring?

Excuse me, I've been hearing a lot about Loopring recently, but I'm a bit confused. Could you clarify something for me? When people talk about Loopring, are they referring to a country? If not, what exactly is Loopring? Is it a cryptocurrency, a blockchain protocol, or perhaps a company? I'm trying to understand its place in the digital finance world and how it fits into the broader ecosystem. I'd appreciate any clarification you can provide. Thank you in advance for your time and assistance.
